CSWP Part Modeling & Assembly Design 3 — Questions and Answers
Question 1: In SOLIDWORKS, the 'Thin Feature' option in Extrude Boss is used to:
- Create a shell from a closed sketch
- Add wall thickness to an open or closed sketch profile (Correct answer)
- Apply a draft angle to the extrusion walls
- Remove material from intersecting bodies
Correct answer: Add wall thickness to an open or closed sketch profile
Thin Feature adds a specified wall thickness to either side of the sketch profile, useful for ribs, channels, or open profiles.
Question 2: Which assembly mate prevents linear motion along one axis while allowing rotation about that same axis?
- Concentric mate (Correct answer)
- Coincident mate
- Parallel mate
- Distance mate
Correct answer: Concentric mate
A Concentric mate aligns two cylindrical axes, removing two translational degrees of freedom but allowing rotation and axial translation.
Question 3: When you apply a 'Mirror' feature in a SOLIDWORKS part, you must select:
- A mirror plane and the features or bodies to mirror (Correct answer)
- Two parallel edges and a midpoint
- A rotation axis and an angle
- A reference point and a distance
Correct answer: A mirror plane and the features or bodies to mirror
The Mirror feature requires a flat face or reference plane as the mirror plane and the features/bodies to be reflected.
Question 4: What is the purpose of the 'Up to Next' end condition in SOLIDWORKS Extrude Cut?
- Cuts through all bodies in the part
- Extends the cut until it hits the next surface encountered (Correct answer)
- Offsets the cut by a fixed distance from a selected face
- Cuts up to a user-specified plane
Correct answer: Extends the cut until it hits the next surface encountered
Up to Next terminates the cut at the first surface the extrusion direction encounters, adapting automatically to geometry changes.
Question 5: In SOLIDWORKS, a 'Base Flange' feature is typically used in which type of part environment?
- Weldment
- Sheet Metal (Correct answer)
- Mold
- Plastic
Correct answer: Sheet Metal
Base Flange is the primary feature used in Sheet Metal parts to create the initial flat sheet from which bends are added.
Question 6: Which SOLIDWORKS relation forces the endpoint of one line to lie exactly on another line or its extension?
- Collinear
- Pierce
- On Curve (Correct answer)
- Midpoint
Correct answer: On Curve
The 'On Curve' (also called 'On Edge') relation constrains a point to lie anywhere on a selected line, arc, or spline.
Question 7: When inserting a component into a SOLIDWORKS assembly by dropping it at the assembly origin, what happens?
- It is placed with a Coincident mate to the top-level plane
- It is automatically Fixed at the origin
- Its origin is aligned to the assembly origin and it is Fixed (Correct answer)
- It becomes a floating component with no mates
Correct answer: Its origin is aligned to the assembly origin and it is Fixed
Dropping the first component at the origin aligns part and assembly origins and automatically applies the Fixed constraint.
